Cosina updates Voigtländer Nokton 25mm F0.95 with clickless aperture

Cosina has announced a slightly revised version of its ultra-fast normal prime for Micro Four Thirds cameras. The Voigtländer Nokton 25mm F0.95 Type II gains an aperture ring mechanism that is switchable between clicked and clickless operation, a desirable feature for movie makers (and previously seen in its 17.5mm F0.95 and 42.5mm F0.95 stablemates). The optics are unchanged, but the updated lens is slightly heavier and larger in diameter. It will be available in March.

Maybe physical aperture? A 25mm f/0.95 lens has a front about 30mm across. But maybe you meant something like an 85mm f/1.4 which would have an actual physical 60mm aperture? But why would this be important to you?

It's a lens for video more than for photo. In video the exposure time is limited by your frame rate, so the extra aperture is much more important than in photo; clickless aperture is also important for smooth transitions – something that's not relevant for still photography.
